The sisters came into the penthouse after their stepmother, Patrizia Reggiani, ordered a successful hit on Maurizio. Reggiani was sentenced to 29 years in prison by an Italian court. The sisters are reportedly selling the penthouse because they spend the bulk of their time in Europe, according to The Wall Street Journal.

On the 51st and 50th floors of the Olympic Tower, the penthouse has 14 foot high ceilings. Since 2010, the sisters have been renting it out for $60,000 a month. Daniela Rivoir of Brown Harris Stevens has the listing.
